This beasty came from a nightmare I had. In my dream, this thing hunted me through a variety of buildings, taunting me as it came along. It had crawled out of a kind of freaky pit when I had failed to stop someone from releasing it into the world.

I don't REALLY have a name for it, even though it's titled Xenogias (no relation to Xenogears, I assure you).

Eventually, I incorporated this thing as the last big-boss enemy in a story I was writing. I wish I could have finished the story properly, so that people could read it. Sufficed to say, this bugger's one of those 'destroy all reality/worlds' kind of monsters (I always wonder how they came up with that; did they just get bored and decide to destroy it all? And then what? XD)
